Performance Pack Oil Pressure PSI?

[NoVaGT]

For those with the PP oil pressure gauge, what is your cold-start oil pressure? Mine is right around 90PSI on a 50 degree day, with Royal Purple in the engine.

That seems a bit high to me.

Once the oil temp is squarely in the middle of the temp range, it idles at about 20-25PSI.

When i start the car its around 90psi but once it warm its down arounf 30ish

Oil psi will show lower once the oil is at normal operating temps (190*-200*) and will (should) remain at a steady psi at idle or when driving in certain RPM ranges.

For my EB PP 6R80 w/3.55's:

Cold start: 80psi+
Hot (normal) idle: 20psi+
Hot (normal) cruising: 40psi+ (and this number fluctuates higher depending on what gear I'm in and at what speed)

O.k., thanks for the feedback. The cold-start PSIs just seemed a bit high.

After 30 years of driving, I'm realizing that engines need longer to properly warm-up than I understood. The oil temp and oil pressure gauges on the PP really educated me.

Mine's about the same, especially on colder days. It'll stay high for several minutes, until the engine warms up, then fluctuate at a much lower level, varying with engine RPM.

Gotta like that Inhgs gauge......whatever it's measuring.

The nice thing is, that if you do a CAI, you can really tell if it does anything. Both in temps and inhgs.

Idle I look for about 25psi.

 

[Boggus]

At idle now in a parking lot - appears to be slightly under 30.

Also, a lot depends on the oil you are running. Brand, type, and especially viscosity.

Yep, high PSI on cold start appears normal. I recall when I bought a '01 Bullitt GT, it had an analog OP gage but was really just a glorified warning light as the needle never moved once acceptable OP was reached. I actually contacted Ford and was told that having an actual OP gage caused too many warranty claims due to owners insisting their was something wrong with their car because the OP fluctuated.......I find that hard to believe but it has stuck with me because a Ford employee stated that was the reason.

That's perfectly logical reasoning.

Hell, I thought something was wrong with my car.

Just warm up by driving gently.
Much better for the car.

Inhgs means how big of a sissy you are. The higher the number, the bigger the sissy.

The lower the number the more tire wear and speeding tickets.

Not sure if y'all are joking, but the "inhgs" gauge is vacuum... common SAE measurement for vacuum is inches of mercury. So the abbreviation is "in. Hg"... 30 inches mercury is full vacuum. 0 inches is normal ambient atmospheric pressure. Goes back to days of liquid mercury barometers, and the length up a tube the mercury would be pushed/pulled by changes in pressure. if you have a turbo/supercharger, this gauge would go up and past the zero. in fact i think the ecoboost models have a psi pressure gauge there instead to show boost. oh and it is measuring vacuum pulled in the intake manifold.
